bview2D assistance

[qi li]

Dear all，

I want to use bview2D to open dump. Follow the recommendations of the official website ,I successfully saw the scalar list in the terminal . But when I type 'box();' in the terminal,no separate window appears .

Could someone help me please?

Sincerely,

Qi

Hi Qi,

you should open the link at the bottom of the field list within your web browser. Please, have a look a this page for a tutorial on Basilisk View (http://basilisk.fr/src/jview/README).

Best,

Gabriele

Hello  Gabriele,

Thank you for your reply. In fact,  I cannot use the interactive basilisk view normally. I can open the URL normally in the browser, but I cannot perform other operations, such as viewing the streaming field. Can't I use the offline Basilisk View now? I am confused.

Regards,

Qi

Attach a screenshot.

Hi Qi,

your screenshot looks fine to me. In order to display a scalar field, you must specify which field you want to plot with the squares function. After you select the squares object from the scene menu, just go to geometry -> color and type the name of the field you want to visualize.

Hope this helps.

Best,

Gabriele

Hi  Gabriele，

Thanks! It works perfectly.  But now I neet a new problem about bview3D . I output the dump file in my flat plate example .   It cannot be opened with bview3D but can be opened with bview2D .In order to reproduce my problem, I uploaded the code of the minimal example . And the terminal command is as follows :

---------------------------------------------------------------------------------------------------------------------------

qcc -autolink -O2 -g -Wall -pipe -D_FORTIFY_SOURCE=2 -DDUMBGL -o dump platedump.c -lm

./dump &

 **new terminal**

Answer myself. It is because I used the mask function with dump. Problem with snapshot in bview2D (google.com)

How can I implement a three-dimensional cuboid computational domain? Any tips? I am considering using embedded conditions ...
